How to bind 64-bit and 32-bit executable into one?

阅读更多关于 How to bind 64-bit and 32-bit executable into one?

问题 Alright so my idea was some way to bind both 64-bit and 32-bit Windows executables into one application so if it doesn't run the 64-bit version it would then try the 32-bit one. I was reading up about PE's and learned a little about MS-DOS Real Mode Stub and it says how it invokes an application (usually an error message). But every time I tried to do research about MS-DOS Real Mode Stub it seemed to only show error messages. So my idea was to overwrite the STUB with my 32-bit application. My

Building iPhone static library for armv6 and armv7 that includes another static library

问题 I have an Xcode project that has a "master" static library target, that includes/links to a bunch of other static libraries from other Xcode projects. When building the master library target for "Optimized (armv6 armv7)", an error occurs in the last phase, during the CreateUniversalBinary step. For each .o file of the libraries that is included by the master library, the following error is reported (for example, the FBConnectGlobal.o file): warning for architecture: armv6 same member name

Under iOS, does anyone know how UUID's are generated for executables and what information may be encoded therein?

阅读更多关于 Under iOS, does anyone know how UUID's are generated for executables and what information may be encoded therein?

问题 Applications compiled on iOS are assigned identifiers (UUID's) at compile time. These identifiers may be revealed by the dwarfdump tool. Does anyone know how UUID's are generated and what information may be encoded within them? 回答1: Almost certainly they're generated by the CoreFoundation UUID machinery, which creates them based off of the MAC address of your ethernet card, the timestamp, and some other miscellaneous information. You can generate your own UUIDs by running uuidgen . As for the

CUDA: How to use -arch and -code and SM vs COMPUTE

阅读更多关于 CUDA: How to use -arch and -code and SM vs COMPUTE

问题 I am still not sure how to properly specify the architectures for code generation when building with nvcc. I am aware that there is machine code as well as PTX code embedded in my binary and that this can be controlled via the controller switches -code and -arch (or a combination of both using -gencode ). Now, according to this apart from the two compiler flags there are also two ways of specifying architectures: sm_XX and compute_XX , where compute_XX refers to a virtual and sm_XX to a real

Proper way to make a fat binary prefer to be 32bit on 64bit OS X 10.6?

阅读更多关于 Proper way to make a fat binary prefer to be 32bit on 64bit OS X 10.6?

问题 Suppose I ask the user "do you want to run in 32bit mode or 64bit mode" and they pick 32bit. How do I register this fact with the operating system? I've looked at the arch command, but I don't want to have to write a script that wraps the binary. I suspect there is a plist-y way to do this, but I can't find documentation (other than arch). 回答1: Try using this Info.plist key, LSArchitecturePriority: <key>LSArchitecturePriority</key> <array> <string>i386</string> <string>x86_64</string> <string

Roll 64-bit and 32-bit versions of an app into the same binary?

阅读更多关于 Roll 64-bit and 32-bit versions of an app into the same binary?

问题 We have an application we're trying to deploy on both 64 bit and 32 bit platforms. Is there a way to put both compiled versions of the code in the same binary, a la Apple and NeXT's fat binaries? Ideally we could ship one .exe that decides upon execution which version of the code to execute. We're targeting Windows XP and later. 回答1: One approach is perhaps to supply a bootstrapping application that determines the architecture and chooses the appropriate executable to run. So basically the

Fat Framework Script for Xcode 10?

阅读更多关于 Fat Framework Script for Xcode 10?

问题 I used this script in the post-action of the archive in my scheme to make a FAT binary framework. One that will work on the simulator and actual device. https://gist.github.com/gauravkeshre/eabb2a13ef6d673fadec84ca60b56b05 Does anyone know how to convert it to work with Xcode 10? Using the legacy build system fixes the errors, but I would rather not rely on it. Here is the script itself: exec > /tmp/${PROJECT_NAME}_archive.log 2>&1 UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}
